Brussels (AFP) - Chelsea's Belgium international midfielder Eden Hazard has fractured his ankle, the Belgian football federation confirmed late on Sunday.

The 26-year-old playmaker sustained the injury training with the national side and will miss Monday's friendly against the Czech Republic and a 2018 World Cup Finals qualifier in Estonia on Friday.

A tweet from his the official Twitter account of his national team read: "Medical imaging showed that @hazardeden10 has a fracture in his right ankle #belcze #estbel #roadtorussia."

Hazard - who helped lift Chelsea to the Premier League title last season - will undergo surgery on Monday and could be out for four months.

Chelsea will be visiting Singapore to play at the International Champions Cup (ICC) from July 25-29 at the National Stadium against Bayern Munich and Inter Milan, and the injury may put Hazard's participation in doubt.
